Verified step by step guidance

Begin by understanding the anatomy of the eye, specifically the location and function of the aqueous humor. The aqueous humor is a clear fluid found in the anterior and posterior chambers of the eye, not between the lens and the retina.

Recognize the role of the aqueous humor in maintaining intraocular pressure. It is crucial for keeping the eye's shape and providing nutrients to the avascular structures of the eye, such as the lens and cornea.

Clarify the production of aqueous humor. It is produced by the ciliary body, not the lacrimal glands. The lacrimal glands are responsible for producing tears.

Differentiate between aqueous humor and vitreous humor. Aqueous humor is a watery fluid, whereas vitreous humor is a gel-like substance filling the vitreous chamber, located between the lens and the retina.

Conclude by identifying the correct statement about aqueous humor: It helps maintain intraocular pressure, which is essential for the proper functioning of the eye.
